Deep Dive
1. Glamsterdam Upgrade (H1 2026)
Overview: This is the next scheduled major hard fork, expected in the first half of 2026. Its core objectives are to significantly scale Ethereum's Layer 1 execution. Key proposals include EIP-7928 for Block-level Access Lists (enabling parallel transaction processing) and EIP-7732 for Enshrined Proposer-Builder Separation (ePBS), which aims to decentralize block building and improve MEV fairness (Ethereum Foundation). The upgrade also plans to push the gas limit "toward and beyond 100 million" from the current 60 million, allowing more transactions per block and lower fees.
What this means: This is bullish for Ethereum because it directly addresses the network's capacity constraints. Higher throughput and lower base-layer fees could improve the user experience for applications that remain on L1 and strengthen Ethereum's competitive position. The main risk is technical complexity, which could lead to delays or implementation challenges.
2. Hegotá Upgrade (H2 2026)
Overview: Following Glamsterdam, the Hegotá upgrade is slated for the second half of 2026, continuing the new biannual upgrade cadence (Decrypt). While its exact scope is still being defined, the focus will likely be on the next phase of state management. This includes advancing Verkle Trees, a data structure crucial for achieving "stateless" clients, which would dramatically reduce the hardware requirements for node operators and bolster decentralization.
What this means: This is neutral-to-bullish for Ethereum as it represents essential, long-term infrastructure work. Successfully implementing Verkle Trees would lower barriers to running a node, enhancing network security and resilience. However, as a complex, foundational change, its development and testing timeline carries inherent uncertainty.
3. The Strawmap Vision (Through 2029)
Overview: Beyond 2026, the Ethereum Foundation's "Strawmap" outlines a strategic vision for Layer 1 upgrades through the end of the decade (The Defiant). It envisions approximately seven forks, targeting five "north stars": near-instant transaction finality, ~10,000 transactions per second on L1, massive L2 scaling, post-quantum cryptography, and built-in privacy for ETH transfers via shielded transactions.
What this means: This is a bullish long-term signal for Ethereum, demonstrating coordinated, multi-year planning to solve scalability, security, and privacy challenges simultaneously. It frames Ethereum's evolution from a rollup-centric present to a fully scaled, quantum-resistant settlement layer. The primary risk is that such an ambitious, multi-year plan depends on sustained research breakthroughs and successful execution of each sequential step.
Conclusion
Ethereum's roadmap is now characterized by a predictable, twice-yearly upgrade cycle focused on concrete scaling, user experience, and security goals, moving from ambitious research into systematic engineering delivery. How will the successful implementation of parallel execution in Glamsterdam reshape the competitive dynamics between Layer 1 and Layer 2 ecosystems?
